Only when the officers and soldiers are united can the army have the same desire and conquer everything; Only by sharing weal and woe can officers and soldiers live and die together. In 1928, Zhu De and Mao Zedong led his troops to successfully join forces in Jinggang Mountains. Since there was little food on the mountain, picking food on the mountain became a regular task. Zhu De was already in his 40s at the time, and as a military commander, he insisted on picking food with the soldiers, crossing mountains and never falling behind. The officers and soldiers saw that Zhu De had to study battles at night and participate in labor during the day. They repeatedly advised him not to pick up grain, but it was of no avail. So everyone quietly hid his shoulder pole. After Zhu De discovered that the pole was missing, he found another one and flattened it with a wooden knife, writing his name on it. The next day, he picked up a new shoulder pole and appeared in the grain picking team. Zhu De's shoulder pole vividly tells us that the reason why our army has been able to maintain strong cohesion and combat effectiveness in the long-term revolutionary struggle is to adhere to the unity of officers and soldiers, sharing joys and sorrows. The core principle of unity among officers and soldiers is to adhere to complete political and personal equality, mobilize and concentrate the wisdom of officers and soldiers, and build a united and friendly revolutionary family. Comrade Mao Zedong pointed out in summarizing the experience of the People's Army in winning battles that our army "has always relied on the unity of officers and soldiers to achieve glorious victories". Practice has fully proven that only when officers and soldiers are united, can the army have the same desire and conquer everything; Through sharing joys and sorrows, officers and soldiers can rely on each other for life and death and gather together to form a united force. From the Agrarian Revolutionary War and the War of Resistance Against Japan, to the War of Liberation and the War of Resistance against the United States and Aid to Korea, to flood control and disaster relief during peacetime, the revolutionary emotions of officers and soldiers, as well as the deep feelings of comrades who share joys and sorrows, are everywhere and always present like air. They have condensed the vast number of officers and soldiers into a combat collective that cannot be defeated or destroyed by any force, inspiring us to be invincible no matter what difficulties and hardships we face Invincible in battle. Honorable traditions cannot be lost, losing means losing one's soul; A good style of work cannot be changed, it only changes its quality. With the profound changes in the era conditions and historical orientation of our military construction, the composition and structure of officers and soldiers, as well as their ways of thinking and behavior, have also shown new characteristics. The problems of unexpected integration, inability to integrate, and inability to work together among cadres and soldiers still objectively exist in a few units, posing a practical problem for the continuation of the excellent tradition of officers and soldiers being consistent and sharing joys and sorrows in the new era. Advancing forward on the new journey of building a strong military, the responsibility of preparing for war and the challenge of transformation and construction require all officers and soldiers to strive, take responsibility for it, and fight for it. The harder the task and the more complex the situation, the more important it is to maintain close relationships between officers and soldiers as an important weapon for defeating the enemy. We must adhere to and firmly adhere to the clear guidance of unity between officers and soldiers, education and management, and strict love. We must build a warm, realistic, and cohesive combat collective, create a good internal environment for upward improvement and fighting for war, and continuously consolidate the "emotional cornerstone" of striving to build a strong military. Amidst all difficulties, it is not difficult for officers and soldiers to share in adversity; Through countless hardships, sharing joys and sorrows from top to bottom means no hardship. In the winter of 1928, He Long led his troops to fight in the deep mountains and forests of western Hunan and Hubei, with very difficult living conditions. Like the soldiers, he was dressed in a single coat and sandals, and could not eat a grain of salt or drink a mouthful of Congee for a few days
